To all whom it may concern.-

Be it known that I, FRANKLIN COPELAND, of Dedham, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Carburetors, of which the following is a specification.

My invention relates to that class of carburetors in which the vapor of hydrocarbon fluids is mingled with air under pressure, and then united with a desired volume of ordinary burninggas and distributed for use, and has for its objects improve-ments in the devices for forming the compound of air and hydrocarbon vapor, which consists in combining in a peculiar manner a series of disks perforated alternately, with a coil of steanrpipes, asteau1- chamber, and a device for regulating the amount of hydrocarbon iiuid,which is injected with the air into the generator. These objects I attain by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical section of my apparatus. Fig. 2 is a cross-section showing the upper oil-tank, its valve, and the air-passage; and Fig. 3 is an elevation showing the front. of the upper oil-tank and the valve indicator hand.

In the drawings, Fig. 1, A represents the generator-case. Within thel case A, I place a number of partitions, B, B', B", &c. These partitions are provided with openings C G', alternately placed, so that the hydrocarbon iluid will have to iiow entirely across each in its passage from pipe P' to the bottom K of the generator. Air under pressure is forced into the generator A through the pipes M P P', Fig. l.

To introduce the hydrocarbon fluid I use the following device:

L is a small tank located at or near the top of the generator, as shown in Fig. 1. The bottom of this tank L is sloped, as shown in Fig. 2, and is provided with a narrow slit, N', at the bottom of which a long revolving valve, N, is placed. (See Figs. l and 2.) The valve N is provided with a number ot' openings, n a' n2, of different sizes, so arranged in relation to the slit N' that but one at a time can be in connection with the oil in the tank L; and as they are of different sizes it may be seen that the amount of oil that can enter the pipe P Application filed December 3, IESS. (No model.)

can be regulated at will by simply turning the valve N.

R', Fig. l, is a hand attached to the valve N, for convenience in turning it, and serves also as a pointer to indicate which of the openings n n' n2 n3 is acting as a duct for the passage of the hydrocarbon fluid from the tank L to the pipe P.

N2, Fig. 2, is aslit, which serves to connect the openings in the valve N with the pipe P, so that the iiuid flowing from the tank L through the valve N will pass directly into the aircurrent in the pipe P, and the iiuid and air will be delivered to the generator A, in combination one with another. This adjustment of the supply of duid to the generator is necessary, as in large establishments it is quite common to light sometimes but one room or iioor, while at other-times more light is wanted. By this device but just the amount of fluid is admitted bythe attendant,who soon learns to set the Valve at the point required.

J' is the main oil-tank, from which the oil or fluid is pumped through the pipe L2 to the upper tank, L.

L' is an overiiow-pipe leading from the upper tank, L, to the main tank J .I is a Siphon-pipe leading from the lower point, K, of the generator A to the tank J', and serves to drain off the fluid or oil from the generator.

D D is a coil of steanrpipes, which pass around the generator, and serve to keep it at the desired temperature, and is provided with inlet-pipe E.

D2 is a steam-chamber, which occupies the whole surface of .the bottom of the generator, and may be filled with steam or hot water. It is connected to the pipe-coil D by the pipes D'E', so that both the coil D and the chamber D2 may be used for heating the generator, or one may be used without the other.

D, Fig. l, is a drip-pipe.

The pipes E', D', and E' are connected by a three-way valve, as shown, so that the steam or hot water may be cut off from the chamber Dz and sent to the waste-pipe E".

H, Fig. l, is a pipe leading from the bottom of the generator, and serves to take the mingled air and hydrocarbon vapor from the generator to a suitable reservoir, vwhere it is IOO mixed with the desired amount of ordinary'y street gas previous to being distributed to the burners.
